He's got talent. You gotta know music to do video.
I'm enjoying the working marine photographers new moves into video. Onne, Black, Allison Langley, it's a whole new world for them(multi media). They already have the eye to see the shot, so they just need to learn to use the tools. Video classes for these pros are available at Maine Media College here in town, and they're popular for commercial photographers.
To see the different boats that I've admired in still photos over the years spring to life under sail, is pretty exciting. Most anyone in commercial photography that doesn't pick up video skills today, takes an early retirement.
I can't wait to see the new tri video. I hope your son throws in some good rap.
